Abstract (en)

Actuating drive (60) has an electric motor (1) for operating of a controlling element (5). Actuating drive is operatable alternatively in a first operating mode or in a second operating mode over a switching device (81). A regulating device (80) regulates the number of revolutions on a first desired value (~W SN) in the first operating mode and a second desired value (~W SL) in a second operating mode. The first desired value is fixed in such a manner that the energy usage is minimum during operation of the control element from a first end position into a second end position. The second desired value is fixed in such a manner that a noise level (L) generated by the actuating drive in the second mode of operation is lower than in the first mode of operation.
